Leaf beetles (<i>Chrysomelidae</i>) are much related to long-horned beetles, however, their antennae do not arise from tubercles and their eyes are not notched.The biology of earwigs (Dermaptera).
Most earwigs (<i>Tenebrionidae</i>) have elongated, flattened, dark brown bodies with membranous hindwings folded underneath short forewings. Most have forceps-like cerci (pichersThe biology of ladybirds (ladybugs, <i>Coccinellidae</i>).

Jumping bristletails (archaeognaths, <i>Archaeognatha</i>) are wingless insects with long three-pronged tails. Tails contain two cerci (paired appendages serving as sensory organs) and an epiproct.The biology of stag beetles (<i>Lucanidae</i>).
Stag beetles (<i>Lucanidae</i>) are characterized by enlarged mouthparts (mandibles) of their male adulti. They use these jaws to fight with other males during mating.The biology of beetles (<i>Coleoptera</i>).
Beetles (<i>Coleoptera</i>) are the largest life form on earth with 5-8 million described species. The invertebrate insects inhabitate most non-marine ecosystems except polar regions.The biology of blister beetles (Meloidae).
Blister beetles (<i>Meloidae</i>) are named after their defensive secretion of cantharidin, an extremely toxic agent causing blistering of the skin and death of animals including horses.The biology of weevils (<i>Apioninae</i>).
Weevils (<i>Apioninae</i>, formerly <i>Apionidae</i>) are closely related to the <i>Curculionidae</i>, but distinguished by clubbed, non-elbowed antennae.The biology of false blister beetles (pollen-feeding beetles, Oedemeridae).
All species of false blister beetles (pollen-feeding beetles, <i>Nitidulidae</i>) are obligate pollen feeders, thus inhabitating flowers of many plants.The biology of glowworm beetles (Phengodidae).
